No, there are no detectable levels of carbon-14 left in any sample older than roughly 40,000 years. Without carbon-14 in the sample, no date can be determined.
Radiocarbon dating is used to date very recent artifacts, and is usually useful only for archeological purposes. It cannot be used to date rocks, both because of its short half life (about 5,000 years), and because it can only be used to date the remains of living things (such as bones, or wood). Rocks are dated using other methods, such as Uranium-Lead dating, which has a much longer half life (over 700 million years).
Carbon dating is a method of telling approximately how old an ancient object is. Here are some sentences.The scientists used carbon dating and decided that the mummy was 10,000 years old.Carbon dating is not perfect, but it can give you a rough idea.We studied carbon dating in class today.
By using carbon 14 dating, scientists can date plants and animals that lived as long as 35,000 years ago.
It isn't 0Carbon dating uses the radioactive isotope Carbon-14 which has a half life of 5730 years. It may be used to date organic materials up to roughly 40,000 years old.BTW, ordinary nonradioactive carbon (Carbon-12 and Carbon-13) by definition have a half life of infinity (not 0), as they do not decay!
About 58,000 years. After that amount of time, there will no longer be enough radioactive carbon in an object to measure. However, other radiometric dating methods can date much older materials.
Here are some sentences.Carbon dating is used to tell the age of a fossil.The scientists performed a carbon dating test.
Just for knowing its origin
400,000 years. I used carbon-14 dating on the bones.
Carbon-14 isotope dating is only effective up to about 70,000 years. Dinosaur bones are at least 65 million years old. Elements with much longer half-lives are used to radiometrically date rock associated with dinosaur remains.
You cannot. Carbon dating is not useful for dating things more than about 50,000 years old. You would have to use a different radioisotope to date something 10 million years old. Potassium-Argon dating would work for some rocks.
Carbon-14 has a half life of about 5,730 years, meaning that it can only date back to thousands of years old. also, the amount of carbon in the earth's atmosphere has been increasing since the beginning of time, so carbon dating is not a very good way to date fossils. Carbon dating only works on things that were once living.Scientists have determined that it would take 30,000 years for the carbon to reach equilibrium, and that the earth is less than 1/3 to equilibrium, so it follows that the earth is less than 10,000 years old.

Carbon dating can be used to date organic materials, such as wood, bones, shells, and charcoal. It is particularly useful for determining the age of archaeological artifacts and fossils that are up to about 50,000 years old.
The benefits of carbon dating is that it can give a guide as to the age of an artifact or fossil. Several problems exist with carbon dating. First, it only goes back so far. After a while, there is not enough radioactive carbon for the machinery to measure. Second, a sample may be contaminated. If a person picked it up with his bare hands, some of the carbon from his skin may have mixed with the sample. Third, if you want to know how long ago a cave was first occupied, you may miss the mark completely. People may have used the same garbage dump for over a million years.
Carbon dating is iused to evaluate the age of organic materials (down to 50 000 years ago).
You do not find the half life in carbon dating. The half lives of carbon isotopes are derived by studying their radioactive decay. For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years.
